Chemical structure

CFTRinh-172

Protocol

Cell experiment [1]:

Cell lines

Fischer rat thyroid cells expressing human wild-type CFTR

Preparation method

The solubility of this compound in DMSO is >20.5mg/mL. General tips for obtaining a higher concentration: Please warm the tube at 37℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months.

Reacting condition

1 mM

Applications

CFTRinh-172 inhibited cAMP/flavone-stimulated Cl– transport in epithelial cells expressing CFTR.

Animal experiment [1]:

Animal models

Mice

Dosage form

250 μg/kg intraperitoneally

Application

A single administration of CFTRinh-172 prior to cholera toxin infusion effectively prevented fluid accumulation in the toxin-treated intestinal loops.

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.

Background

Ki: 0.3 to 5 μM for channel opening

The cystic fibrosis (CF) transmembrane regulator (CFTR) is a cAMP-activated Cl channel expressed in epithelial cells of the lung, intestine, pancreas, and other tissues, where it facilitates transepithelial fluid transport. CFTRinh-172 is a highly potent and selective CFTR inhibitor.

In vitro: CFTRinh-172 could reversibly inhibit CFTR short-circuit current in less than 2 minutes in a voltage-independent manner. Moreover, at concentrations fully inhibiting CFTR, CFTRinh-172 did not prevent elevation of cellular cAMP or inhibit non-CFTR Cl–channels, multidrug resistance protein-1, ATP-sensitive K+ channels, or a series of other transporters [2].

In vivo: A single ip injection of CFTRinh-172 (250 μg/kg) in mice reduced by more than 90% cholera toxin–induced fluid secretion in the small intestine over 6 hours. CFTRinh-172 may be useful in developing large-animal models of cystic fibrosis and reducing intestinal fluid loss in cholera and other secretory diarrheas [3].

Clinical trial: Up to now, CFTRinh-172 is still in the preclinical development stage.
